+ * Name: up_initialize
+ *
+ * Description:
+ *   up_initialize will be called once during OS
+ *   initialization after the basic OS services have been
+ *   initialized.  The architecture specific details of
+ *   initializing the OS will be handled here.  Such things as
+ *   setting up interrupt service routines, starting the
+ *   clock, and registering device drivers are some of the
+ *   things that are different for each processor and hardware
+ *   platform.
+ *
+ *   up_initialize is called after the OS initialized but
+ *   before the init process has been started and before the
+ *   libraries have been initialized.  OS services and driver
+ *   services are available.
+ *
